ok i have a suzuki forenza 2006. i was installing a car alarm and i got everything to work perfectly lights too. so i take the car for a spin making sure things work fine turn it on off get out test the doors you know everything. well one time i started my car and on the way back from around the block i herd a click from my alarm module and my lights cut off. i have not been able to get them to work since. the high beams work the blinkers work the day lights work. So the low beams and inside the car the speedometer doesn't light up. in the instructions it said connect some purple wire to my parking lights which are in my headlight switch. i found three wires a white plug thing a black one a green and black one and a white one. i connected the purple wire to the white because when i probed it it went from pos to neg when i turned on my parking lights. Well turns out the alarm module was set up for positive parking lights and i have negative so i guess that did SOMETHING to my lights. well i switched the alarm module to negative parking lights. and now when i lock or unlock the doors the parking lights and the speedometer lights up. but while driving and i try to turn on the lights nothing comes on. the only way to get the speedometer to light up is by pressing a button on my remote, and the headlights never come on. all the fuses look good. i talked to a guy and he said it may be my headlight switch. CAN ANYONE HELP ME. either fix what is wrong or tell me an inexpensive fix. figured the dealer would say i voided the warranty by trying to do it myself.
